Flutter Frenzy is an interactive cat toy with a patented bird that chirps to mimic the sound of a wild bird to stimulate your kitty. The magnetic, unpredictable bird movement stimulates your cat's inner hunter instincts, and has a 360 degree design that allows for multiple cats to play. Flutter Frenzy has a wobble base that ensures the toy stands upright during play, and shuts off automatically after 10 minutes.
